'Toall 'whom t may concern.

Be it known that I, THOMAS BReNsoN, a

i citizen of the United States, residing in Philadelphia, in the countyof Philadelphia and` State of' Pennsylvania, have invented certain newand useful Improvements in Reinforcing Fabric Strips for Tires, whereofthe following is a specification, reference being had to theaccompanying drawings.

The invention relates more particularly `to a fabric strip for tireswhich includes a series of substantially straight parallel cordsextending lengthwise of the strip.

An object of the invention is to provide a strip wherein the parallelcords extending lengthwise thereof and forming the body portion of thestrip are connected by threads which are so arranged that the strip maybe cut lengthwise without disintegrating said cut portions.

A furtherobject of the invention is to provide a reinforcingl fabricstrip of the above character .wherein the connecting threads includerows of enchained loops extending lengthwise of'the strip, whichenchained loops are suiiiciently' elastic to permit the cords when undertension to lie straight. y

A still further Vobject of the. invention is to provide a.reinforcingfabric of the above character wherein the connecting threads includeseparated rows of enchained thread loops and-connecting binding threadswhich join the 'rows of loops.

These and other objects will in part be obvious and will in part behereinafter more y fully disclosed.

In the drawings, Figure I, is an enlarged plan view of a fabric havingmy improvements embodied therein.

Fig. II, is a similar view but showing aA slightly modified form ofarrangement of the connecting threads which sustain the,

cords are not only liable to pile one on topof the other, but the stripsmust be made in the exact width in which they areto be used.' Thepresent invention is directed to the improved way of joining the cords'wherein the cords are held from pilin one ontop of the other, andwhereby the abrio integrating the cut portions. I have acconiplishedthis connecting of the cords in the present .embodiment of the inventionby using a series =of rows of separately enchained thread loopsextending longitudinally of the strip and 'connecting these en chainedthread loops by binding threads, said enhained loops and binding threadsbeing disposed between and about the'coids so as to join the saine toform the fabric strips.. v

Referring more'in detail to the drawings, I have shown my improvedreinforcing fabric strip as consisting of a series of cords 1, whichextend substantially straight and parallel with each other andlengthwise of the strip,-which is to 'be embodied in the tire. In theform of the invention shown in Fig. I, I- haveprovided a series of rowsof enchained thread loops 2. These rows of loops are each separatelyenchained and extend lengthwise yof thev fabric strip. In

other words, the enchained series 2, consists next loop 4, and thisloop. 4, encircles the base of the loop 5.V The loop 3, is brought fromunderneath the cord 1, at one side thereof, and extends across the cord.The loop, 4, is brought from underneath the opposite side ofthe samecord and extends across the same, and the loop 5, isagain brought yfromnnder the same side of the cord 1, as

the loop 3. Thus it will be seen that these enchained loops willcompletely envelop one of the cords. Two binding` threads are used.

These 'binding threads are indicated at 6,

and 7 and pass through one or more of the enchained loops extendingabout one of the cords, and then across to the next row of enchainedloops extending about another cord. Preferably-between the bindingthreads 7, and 8, isz a cord 1, so that alternate cords are enveloped bythe enchained loops, and

and these alternate cords extend between the lot binding threads.

strip may be cut longitudinally without disi Itwill readily be seen thatif this fabric strip formed as shown in Fig. I, is put under tension,the enchained loops being elastic will yield suiiici'ent so as to allowthe cords to lie each other and prevent said cords from pil? ing one ontop of the other. By cutting the binding threads between two of thecords7 Athe strips may be cut longitudinally and the enehained loopsform a selvage edge which prevents thecut portions from disintegratoutwhen the strip ing. Of course, it is understood that the cord held onlyby the bipding threads would drop is cut. This fabric strip may be madein any desired width most convenient to manufacture, and then may be outto any desired width for use, depending upon the size of the' tire intowhich it is to be embodied. i

In Fig. II, of the drawing, I have shown a slightly modified form of theinvention. The enohained loops indicated at 8, are similar inconstruction tothe enehained thread loops indicated at 2,`in Fig. I,with the exception that these enchained thread loops do not envelop thecord. The binding threads indicated at 9, and 10, are arranged slightlydifferent from that shown in Fig. I. I have also shown two cords in thismodification of the invention between two adjacent rows of enehainedthread loops 8. thread 9,v passes over the two cords, while the bindingthread 10, passes underneath the same. Thus the cords are held throughthe combined action of the enehained loops and y the cords may be madewithout departing' the binding threads. v

It will be obvious that other n'iodifications in the general arrangementof the enchained thread loops and binding threads and also from thespirit of the invention? The essential feature consists in connectingthe threads for sustaining the cords so that the cords may be placedunder tension and lie straight without bending, and so that the fabricstrip may be Acut longitudinally without disintegrating the eut sectionsof the strip.

ltween the adjacent rows of enehained loops,

The binding necting said enehained thread loops, said enchained threadloops and. binding threads being dlsposed so as to connect and hold saidcords, whereby said strip may be cut in a lengthwise direction betweenalternate binding threads.

2. A reinforced fabric strip for tires, comprising a series of straightparallel cords, extending lengthwise of the strip; a series ofseparately enehained rows of thread loops extending lengthwise of thestrip; and binding threads extending back and forth besaid enchaincd.loops, and binding threads being disposed so as toconnectand hold saidcords.

3. A reinforced fabric strip for tires, oomprisin g a series of straightparallel cords extending lengthwise of the' strip; a series ofseparately enehained rows of thread loops each disposed so as to envelopone of said cords, and eonnectingfbinding threads joining adjacent rowsof enehained loops.

4. A. reinforced fabric strip for tires, com; prising a series ofstraight parallel cords eX- tending lengthwise of the strip; a series ofseparately enohained rows of thread loops extending lengthwise of thestrip, said enchained thread loops being disposed so as to envelopalternate cords and binding threads joining rows of enchained loops,said binding threads being disposed so as to embrace and hold theintermediate cords between the rows of cnchained thread loops.

In testimony whereof I have `hereunto signed my name at Philadelphia,Pennsylvania, this eighth day of March, 1918.
